The Technology Refresh was an announcement of capabilities that are both available (for the core OS) or will be available in the future (Zend Server and maybe other stuff I'm not 100% sure). In this case the Zend Server release in not part of anything that can be downloaded at this time.

As stated - Zend Server for IBM i Version 6 supports the development of mobile applications as well as providing capabilities for application awareness, auditing, and authentication.

The availability of TR6 was February 26, 2013
